1、電纜橋架主要用于敷設電力電纜和控制電纜，線槽用于敷設導線和通訊線纜；
1, cable bridge is mainly used for laying power cables and control cables, wire slot used for laying wire and cable;
  2、電纜橋架相對大（200×100到600×200)，線槽相對較??；
2, cable tray is relatively large (200 × 100 to 600 × 200), slot is relatively small;
  3、電纜橋架拐彎半徑比較大，線槽大部分拐直角彎；
3, cable bridge turning radius is relatively large, slot parts at a right angle bend;
  4、電纜橋架跨距比較大，線槽比較??；
4, cable bridge span is relatively large, relatively small line groove;
  5、橋架與線槽的固定、安裝方式不同；在某些場所，橋架沒蓋，線槽通常全是帶蓋封閉的線槽來走線，橋架則是用來走電纜的。
5, the bridge and the groove of the fixed, installed in different ways; in some places, the bridge did not cover, line groove is usually full line groove belt cover closed to walk the line, the bridge is used to take the cable.
